3 Claims.

This invention relates to a valve particularly of the type for controlling how of water, and it has to do with a valve of the faucet type wherein the movable valve member shifts against the direction of flow of the water when the valve is opened and shifts with the direction of movement of the water when the valve is closed.

An object of the invention is to provide an improved valve or faucet construction wherein a valve of the type mentioned has an anti-friction bearing arrangement interposed between a rotatable control member and the valve seal. In accordance with the invention the valve embodies a rotatable valve controlling member mounted on threads so that it shifts axially and it is connected by means of an anti-friction hearing to the valve sealing member, so that when the sealing member comes to rest upon its seat, it may sit thereon without rotation while the controlling member is turned on its threads to tighten the engagement.

A valve constructed in accordance with the invention is shown in the accompanying drawings:

Fig. l is a view largely in cross section showi ing a valve constructed in accordance with the invention.

Fig. 2 is a plan view of a stem sealing member.

Fig. 3 is a view largely in elevation with some parts cut away and parts shown in section showing the controlling member and valve seal mounted thereon.

Fig. 4 is a cross sectional view taken substantially on line 4-4 of Fig. l.

The valve has a body l with an inlet passage 2 leading to a chamber 3. The body has an outlet passage 5 in a suitable extension or spigot 6. An extension 1 is externally screw threaded as shown for the reception of a' cap 8 apertured as indicated for the passage therethrough of the controlling stem.

Situated within the body is an insert or cage Hi. This cage is generally of cylindrical form and is positioned by means of an internal shoulder 12 in the body with an interposed sealing washer l3. The bottom portion ofthe cage constitutes a partition and is provided witha valve seat 15 surrounding or bounding a valve opening Hi.

This cage is provided with ports it generally in alignment with the outlet passage 5 In this connection the body may have an enlargement providing a passageway I9 which is in registry with the ports and also with the outlet passage 6 shown in Fig.4.

The cage is internally threaded as at 20 and is arranged to be held against the shoulder 42 or interposed sealing member 13 when the cap 8 is tightened to the body.

An operating stem 22 with a suitable handle 23 extends through the cap and this stern may have an integral body portion 25 with threads 26 engaging the threads 20. The body portion is hollow as shown at 30 in Fig. l and it has a depending circumferential flange 28.

The hollow or cavity 30 is partially defined by the circumferential flange 28. It has disposed therein the head portion 3| of a valve seal stem 32. This construction provides a chamber on the side of the valve passage l6 opposite the chamber 3. The head 3! has a thrust transmitting connection with the operat'ng stem and as shown in Fig. 1 this takes the form of a single ball 31 disposed between the end of the head 31 and the top of the cavity til which in eiiect is at the end of the stem 22. At the intersection of the valve seal stem 32 and the head 3! there is formed a race formation for receiving an annular array of balls M which operate thereon. An oppositely disposed race member 52 is secured to the depending flange 28 as by means of fashioning the end of the flange over the race 42' as shown at 43. This race member 42 is engaged against and located by the shoulder on the interior of the flange 28.

The stem 32 projects through the valve pas sage Hi. It is provided with a shoulder 55 for locating a seal member l? which may be of suitable rubber, either natural or synthetic or of other material, and which is held in posiiton by a retainer 48 held by a nut 49.

A stem seal member is illustrated at at. This" member is in the form of a disc of natural or synthetic rubber. It is disposed under the cap as shown with the stem 22 passing through the central aperture 5! therein. Underlying the sealing washer 59 is a washer 52. The aperture in the washer 52 is larger than that in the sealing member be as indicated. One form of construction is to provide the aperture 5! in the washer 59 of a smaller diameter than that of the operating stem 22. Therefore, the inner zone of the sealing washer is flexed inwardly as shown to embrace the stem 22. On the other hand, the washer may be preformed to the shape as substantially shown in Fig. 1. Suffice it to say that when the valve is open, the stem sealing washer 5B prevents escape of water around the stem.

The valve is shown in closed position in Fig. 1.

to its threaded mounting, it shifts downwardly as Fig. 1 is viewed, thus removing the seal memfrom its seat. Water may thus flow from the chamber 3 into the chamber 35 and out through the spigot. As mentioned above, the water is prevented from escaping around the the sealing washer 50. In the opencage.

I claim: 1. In a valve having a valve body with a chamber therein and an inlet passage and an ber on said shoulder, the inner member having internal threads, the partition having a valve opening therein bounded by a valve seat, e.

operating member having a body part disposed within and mounted on the threads of the inner partition dividing the chamber into an inlet section and an outlet section connecting respectivecn said shoulder, the inner member having inmounted on the threads of the inner member on.

seal member axially for moving the seal member to and from engagement with said seat.
